今天下午写了一个流水灯闪烁的实验，总的来说，不难，因为这块板子集合的电路图没有上一块那么复杂，所以总的来说，还是比较顺手，开始的时候，出现流水灯没有流转的现象，原来是没有加入延时函数，后来经过调整，结果很快就出来了

电路示意图：

示例代码：

#include<msp430x14x.h>#define CPU_F ((double)8000000)
#define delay_us(x) __delay_cycles((long)(CPU_F*(double)x/1000000.0))
#define delay_ms(x) __delay_cycles((long)(CPU_F*(double)x/1000.0))
unsigned char table1[]={0xfe,0xfd,0xfb,0xf7,0xef,0xdf,0xbf,0x7f};void main( void )
{
// Stop watchdog timer to prevent time out reset
WDTCTL = WDTPW + WDTHOLD;
unsigned char i=; P2SEL = 0x0;//设置P2普通的I/O
P2DIR = 0xff;//设置普通的输出 while()
{
P2OUT = table1[i];
delay_ms();
i++;
if(i == )
i=;
}}
